Crystals Procurement Notes

Verify the specific load capacitance requirement of your circuit design against the component's 8 pF specification before procurement. Ensure that the PCB layout accommodates the 4-SMD no-lead footprint dimensions accurately. Confirm that the operating environment remains within the specified -20°C to +70°C temperature range to maintain the stated ±15 ppm frequency stability. Cross-reference the manufacturer datasheet for soldering profile recommendations to ensure reliable joint formation during assembly processes.

Crystals Selection Notes

Select this component when a 48 MHz fundamental frequency with 8 pF load capacitance is required for space-constrained designs. The 4-SMD no-lead package offers a smaller footprint compared to traditional leaded crystals, making it suitable for high-density PCB layouts. Consider the ±15 ppm stability rating against system timing requirements. Verify compatibility with standard surface mount reflow soldering profiles and ensure the ESR value aligns with the oscillator circuit's drive level limitations.

Crystals Part Context

This part belongs to the 402 Series of surface mount crystals from CTS-Frequency Controls. The series provides various load capacitance options including 6pF, 8pF, 9pF, 12pF, and 18pF variants to match different oscillator circuit requirements. All members share similar physical dimensions and electrical characteristics such as ESR and frequency stability, differing primarily in load capacitance values.

Crystals Replacement Considerations

Direct substitutes include other 48 MHz crystals with 8 pF load capacitance and identical 4-SMD no-lead footprints. Equivalent parts from other manufacturers must match the 60 Ohm ESR and ±15 ppm stability specifications. Verify that alternative components support the same operating temperature range and are compatible with the existing PCB land pattern.
